    I have the equivalent of a SCIV, and a 1057 converter. It handles my 350 PPE tune without problem. A properly installed SCIII will do fine with a 270 PPE tune.

    What year is your truck?

    ...Damn, if you are going to be using the 350 Tune to pull, I'd think your EGT's would be through the roof!

    Hell, I'd say no more than a 120hp tune for pulling. Of course it depends on what you are pulling. If you are pulling something so light the Truck won't even know it's back there, then yea, a 350hp tune will do.

    How much weight are you planning on pulling?

    Ok, I have 0 experience with pulling contests, so I'll back down, but if it were me, I'd still only run the 120hp.

    But people say you are good at a certain Max EGT for XX amount of time, so I'll let the experienced pullers step in.

    Just let everyone here know what your current / expected mods. will be at the time of the pull so it will give them a good guess as to what would be safe for you.

    Just incase you didn't know...
    *Horsepower numbers are represented at the crank.
    This is true for ATS and PPE

    I run a RWHP 230 tune when I sled pull.
    I run a RWHP 40 tune when I tow the TT.

    pulling and towing are two different animals. i wouldn't hardly worry about your EGT's when you're pulling a sled down the track, as that's only 5-10 seconds and then your EGT's will drop after that. towing a camper for 500+ miles at a time is different. then i'd be worried about cooking my turbo while running a hot tune.
